A Kelowna, B.C., woman whose supervisor slapped her on the backside and offered her marijuana, lingerie and truck tires in return for sex has won a $32,000 award after a decision by the B.C. Human Rights Tribunal.

The tribunal heard that 27-year-old site safety officer Kori Harrison was also encouraged to dress sexier while she worked at a construction site in 2005.

The complaint was against her supervisor, Greg Ford, Calgary-based companies Navigator Development and Con-Forte Contracting, and Harrison's employer, Nixon Safety Consulting.

Tribunal member Kurt Neuenfeldt said in his written decision that Ford sexually harassed Harrison and that Nixon Safety Consulting fired her when she complained.

Neuenfeldt said Harrison needed the job as a single mother of three and that Ford knew or should have known that his behaviour was inappropriate.

Harrison started her job in October 2005 and by December had complained to the site superintendent and her employer.
